I'm thinking about getting a set of the scissors and tweezers. I've seen them in 24, 12, and 4-6 inch lengths. Just wondering, what people's experiences have been using the various lengths of scissors and tweezers. My tank is the typical 22-23 inches deep.

Some openning questions for thought...

Is longer better or a pain because they are hard to work with?
Do shorter give you better control?
Are you going to get wet anyway so it doesn't matter?
